TES PATENT OFFICE EUGEN HIN'DERER, OF HAMBORN, GERMANY, ASSIGNOR TO VEREINIGTE STAHLWERKE AKTIENGESELLSCHAFT, OF'DUSSELDORF, GERMANY, A CORPORATION OF GERMANY MEANS FOR SEPARATING ADHERING ROLLED METAL SHEETS Application filed January "I, 1927, Serial No.

In rolling mills for metal sheets, a large number of the latter becomes useless by the fact that the rolled, at least double metal sheets adhere so fast to one another that they cannot be separated but with extremely great difliculty, which is further increased if the metal sheets are at some places welded to one another.

The present invention provides improved means for effecting said separation in a mechanical way, by pulling said sheets over a contrivance engaging between said sheets and receiving a rockingor (and) rotary motion,v said'contrivance consisting preferably of one or more cutterlike bodies of suitable crosssection, eventually in combination and coacting with stationary cutters, and which, if consisting of a pair of cutters, are driven to receive a rocking motion like that of'thetwo members of a pair of tongs; the introduction of the metal sheets into the device for pulling the same over the separating contrivance being eflected'by means of splitting magnets and intermediary guides. y The accompanying drawings illustrate how the invention can be put into practice Figs. 1 and 2 show, by way of example, a side view and a fragmentary plan view respectively of a preferred constructional form of an apparatus for effecting the separation of the adhering metal sheets; Figs. 3 and 4 are cross-sections, respectively on the lines 3-3 and 44 of Fig. 2; and Figs. 5 to 14 are diagrammatical cross-sections through various forms of the movable separating con trivance and of the metal sheets during their movement over thelatter.

Referring to Figs. 1 to 4 inclusive The adhering rolled metal sheets are first split open at their front ends and with the joint thus formed placed over the separating contrivance consisting, for instance, of a pair of cutters a receiving a rocking motion like thatof the members of a pair of tongs. Behind said contrivance the 'two metal sheets are caught by tongs b which pull the same over said contrivance by means of cords a wound on a drum-d connected with an electromotor f by means of a toothed gear e. Another motor .9 effects the rocking motion 159,735, and in Germany August 19, 1926.

(see full-line and dotted-line positions of the same). v

Fig. 6 shows one rotary round body. Fig. 7 shows one wedge-shaped cutter only and dotted-line positions of the same).

Fig. 8 shows a rocking or rotary body of square cross-section.

Fig. 10 shows a pair of round bodies rotating in opposite directions.

Fig. 11 shows a rotary round body in combination and co-acting with an immovable cutter. r

Fig. 12 shows a rotary round body in combination and co-acting with a rocking cutter.

Fig. 13 shows a rotary body in combination with two pairs of wedge-shaped cutters for separating four superposed adhering metal sheets rolled in common.

The initial separation of the metal sheets at their front ends, for obtaining the joint with which they are placed over the separating contrivance, can be effected either by hand, .or, as this is rather cumbersome and time-wasting, preferably also by a mechanical contrivance such as tratedin- Fig. 9.

The two rolls Z therein lead the metal sheets first between two magnets m whereby the sheets are split open at their front ends and then passed along guides 11. over the separating contrivance a and caught by the tongs b, the guides and magnets being then removed and the sheets normally moved over the separating contrivance by the pulling cords c.

for instance illusperforming a rocking motion (see full-line I Fig. 14 shows the arrangement of the two magnets m within the rolls Z.

I am aware that it has been proposed to' separate adhering rolled metal sheets by means of an immovable spreader bar engaging between the same during their advance andI distinctly disclaim any use of the sai known means separately.

, What Iclaim, is

1. An'apparatus for separating adhering rolled metal sheets comprising in combination a device engaging between the sheets to be separated, means for pulling the sheets over said device, means for imparting to said device a separating motion during the travel of the sheets over the device, and immovv able cutters coacting with said movable separating device.

2. An apparatus for separating adhering rolled metal sheetscomprising in combination a device engaging between the sheets to -be separated and consisting of a pair of cutters, means for pulling the sheets over said device, and means for 'im arting to said pair of cutters a tong-like roc lxing motion.

3. An'apparatus for separating adhering rolled metal sheets comprising in combination a separating device engaging between the sheets to be separated, means for imparting an oscillating movement to said device, a drum, c'ables'adapted to be wound on the drum, and means for attaching the front edges of the metal sheets to the cables.

4. In anapparatus for separating adhering rolled metal sheets, a separating device comprising a pair of cutters journalled inthe frame of the apparatus, and means for impartin to the cutters a rocking motion like that o the two members of a pair of tongs.

In testimony whereof I have hereunto set my hand.
